Summer project - connecting Raspberry Pi to Robobuilder. Uses an expansion board to access UART and a level shift for voltages. Also RPi is powered through GPIO from a 7805 fed from the same power supply that drives servos.

Setting up the nanoBT usb to allow remote access is proving hard, so using Ethernet cable. Next steps are to look at connecting accelerometer via I2C and may be the distance sensor as well as custom 3D printed case.

So much more powerful than the RBC box ! I have it running my Basic to control the robot (just a simple recompile) so it can walk etc, but RPi comes with Python as well Wolfram etc all built in so may look at a wck library for that.

The amount of resources available in websites, books, clubs make RPi such a good choice. I'm currently putting the schematic into DesignSpark CAD program so will publish that when its done - but might be a few weeks (at least)

What to do with the extra power? Well I have connected a webcam up and that worked immediately out of the box and have mjpeg streamer running so I can process video images. So current projects I'm think off are:1. Build a football playing robot, i.e. find a ball, track it, walk to it and kick it. (sounds simple doesn't it?)2. Track a ping pong ball and see if I can get it to swing arm and hit it. ( This might be easier as robot can be stationary.)

Hi,It will work with servos, as the head on my robot uses the little servos that RQ-HUNO uses. In terms of schematics, connect the serial I/O on the Raspberry to the RX/TX lines on the servos. There's plenty of web pages to explain how.

I think the Huno may be too small though to carry the weight of the RPi - May be look at using the Pi-zero? I now have a Raspberry Pi 3 and I'm printing a custom 3D case to sit on back of the 5710. This should be a powerful combination.

cheers
